I know there is very little information about this programme, but, in attempt to learn more about it, I would be curious to see who else hears what I am hearing. Do these episodes not sound very much like the same actors and production company as the Tarzan serials, such as The Diamond of Asher and The Fires of Tohr? Professor Anton Edwards to me sounds so definitely to be Cy Kendall,
i.e. the fellow who played Atan Thome, and the sound effects sound exactly like the ones used in the Tarzan serials. Even the narrator sounds like the same voice. Is there any other information that would link them? Am I the only one hearing this? I would love to know more about this programme.
